# Fin Toe Angle Effect Analyzer AI Agent Connect

> Fin Toe Angle Effect Analyzer MCP gives your AI client the math needed for surfboard and hydrofoil design. It calculates how fin geometry and toe angles impact drag, drive, and release. Instead of guessing how a new fin setup will feel, you can use these tools to get specific drag coefficients and grip-to-looseness ratios before you ever cut a board.

## Description

Designing high-performance boards requires precise control over how water moves around the fins. This MCP gives your agent the ability to run hydrodynamic simulations on fin configurations. You can move beyond intuition by calculating exactly how a change in toe angle affects the drag coefficient or the balance between drive and release. Whether you are tweaking a high-aspect foil or a performance surfboard, you can use these tools to model how different geometries behave at specific speeds. It turns your AI client into a specialized engineering partner that can compare two different setups side-by:side or find the exact angle needed to hit a specific performance target. You get hard numbers on grip and looseness, allowing for much tighter design iterations.

## Tools

### analyze_hydrodynamic_balance
This tool determines the balance between drive and release based on your fin configuration. It tells you if a setup will feel grippy or loose.

### calculate_drag_impact
Use this to predict how a specific toe angle adjustment changes the drag coefficient. It quantifies the cost of changing fin orientation.

### compare_fin_configurations
This tool evaluates two different fin setups side-by-side. It helps you see which configuration performs better under your specific conditions.

### find_optimal_toe
This tool identifies the best toe angle to reach a specific performance goal. It solves for the angle that hits your target drive or release.

## Prompt Examples

**Prompt:** 
```
What is the balance of drive and release for a Swept fin with a 5 degree toe angle and 2 degree cant at 15 knots?
```

**Response:** 
```
The configuration provides a drive score of 0.85, a release score of 0.30, and a stable rating.
```

**Prompt:** 
```
How much will my drag change if I move from a 3 degree toe angle to a 7 degree toe angle on a HighAspect fin at 20 knots?
```

**Response:** 
```
The drag coefficient will increase by 0.045, resulting in a total estimated drag of 1.25 units.
```

**Prompt:** 
```
Find the best toe angle for maximum drive using a Pivot fin with 0 cant at 10 knots.
```

**Response:** 
```
The optimal toe angle for maximum drive is 4.5 degrees, which yields an expected drive score of 0.78.
```

## Capabilities

### Drag Prediction
Your agent calculates the change in drag coefficients when you adjust toe angles.

### Performance Balancing
The AI determines the ratio of drive to release for any given fin setup.

### Setup Comparison
Your client compares two different fin geometries to see which one meets your criteria.

### Angle Optimization
The agent finds the specific toe angle required to achieve a target performance level.

## Use Cases

### Optimizing Drive
Find the exact toe angle needed to maximize drive for a specific fin type.

### Reducing Drag
Calculate how much drag you add when increasing the toe angle on a high-aspect fin.

### Testing New Setups
Compare a new fin geometry against an existing one to see the performance difference.

### Balancing Feel
Determine if a fin setup will be too loose or too grippy for a specific speed.

## Benefits

- Quantifies the relationship between toe angle and drag coefficient.
- Provides a mathematical ratio for drive versus release.
- Eliminates guesswork in fin orientation adjustments.
- Enables rapid comparison of multiple fin configurations.

## How It Works

Connect the MCP to your AI client and start running hydrodynamic calculations immediately.

1. Connect your client to the Vinkius-hosted MCP.
2. Provide fin geometry, toe angle, and speed to your agent.
3. The agent calls the relevant tool to run the math.
4. Receive specific data on drag, drive, or optimal angles.
